TIRE.

Specification of Letters Patent.

Patented Sept. 28, 1909.

Application filed January 26, 1909. serial No. 474,825.

To all whom it may concern:

Be it known that I, LoUIs M. NELSON, a citizen of the United States,residing at Douglas, in the county of Converse and State of Wyoming,have invented certain new and useful Improvements in Tires, of which thefollowing is a specification.

The object of my present invention is an improved construction of tirefor the wheels of automobiles or other vehicles, which will embody to amarked degree the characteristics of strength, durability and capabilityof resisting t e abrasive and cutting action of a roadway, and whichwill be also noted by the fact that it possesses a maximum resiliency atthe tread and a adually decreasing resiliency toward thfio ase, the basebeing practically solid, as will be hereinafter pointed out. 1

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which:

Figure 1 is a longitudinal sectional view of a portion of a tireconstructed in accordance with my invention, some of the parts beingexaggerated to bring out their distinctive features; and, Fig. 2 is atransverse sectional view of the tire.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by thesamereference characters.

My improved tire may be of any desired size and cross section, shape ordesign, according to the particular wheel or wheel rim for which it mabe intended, and it embodies a series of brous sections 1 com-.

posed of a textile fabric, such as cotton duck, and interposed andalternating layers 2 of rubber. I are so cut on the bias that the fibers'or threads will extend obliquely,as indicated in Fig. 2, therebypreventing fraying of the I claim is:

The cotton duck sections 1- threads when the tire is being used, theends of the threads receivin all" of the wear. In the manufacture of t etire, these alternating layers of rubber and cotton duck are molded andvulcanized to ether, the rubber permeatin the fibers of t e sections 1,and the tire, w en completed, comprising an integral structure. Thesections 1, are, of course, the same thickness throughout, and are soplaced in a fan-shape relation to each other, that. the rubber sections2 gradually decrease in thickness from their outer edges to their inneredges, preferably terminating at their inner edges ust short of theinner edges of the sections 1, but close enough to the inner edges ofthe sections 1 to effectually Waterproof the base of the tire, while atthe same time it Will be manifest that the tire so constructed possessesits maximum resiliency at the tread, while the base is practicallysolid.

This is the primary object of my invention, and one which isefi'ectivelyattained.

Having thus descrihed the-invention. What As a new article of mans facture, the herein described tire consisti g of alternatin layers ofnon-resilient fibrous material and rubber, the rubber lay ers decreasingin thickness from their outerfedges toward their inner edges and suchinner edges terminating just short of the inner edges of the first namedlayers, the inner edges of the first named layers abutting against eachother, whereby the tire is formed with an elastic tread surface whichdecreases in resiliency near its base where it is substantiallynonresilient.

In testimon whereof I aflix my signature in presence 0 two witnesses.
